Full Changelog

• BC Break: Removed the source-fallback config option which was added in 2.10 as a temporary measure, dist installs no longer fall back to source (#13050)
• Security: Fixed package names in vendor/composer/installed.json being able to escape the vendor directory during install and reinstall (GHSA-c968-33g3-wh7p)

• Improved explanations for versions blocked by security advisories in dependency conflict errors (#13108, #13075)
